Uber's new car-sharing service saw 45,000 trips in London during its first week of operation.
UberPOOL, which went live in the capital on December 4, allows people to share a car and save money when getting from A to B.
The service was introduced in London after success in other major cities around the world, including San Francisco, where it was launched in September 2014, and Paris.
Uber says almost two-thirds of its drivers in the city carried out a shared journey in the opening week.
Tom Elvidge, the company's London general manager, claims Londoners are saving money and reducing mileage by sharing their journey with other people going in the same direction.
He adds the service will make it easier and cheaper for people to leave their own cars at home, reducing the number of single-occupant vehicles on the road.
Passengers using UberPOOL stand to save 25% compared to the standard uberX fare, Uber's most affordable option.
Each pick-up is restricted to a maximum of two people, with no more than three passengers allowed in a car at once.
